This invention relates to coin deliveryapparatus, and is particularlydirected to a locking means therefor.

In coin delivery apparatus, as heretofore known, it has been the usualpractice to provide a plurality of coin hoppers or chutes in which thesupply of coins is stacked. These devices are also frequently providedwith means for locking the dislodging plungers against action whenthecoin supply becomes nearly exhausted. Means have also been providedfor latching the locking means out of operative position when desired.These machines, however, had the defect of permitting the latching meansto retain the locking means out of operative position continuously afterthey hadbeen once set, until manually released by the operator. Further,these machines had the defect of imposing a considerable lateralpressure against the coins which sometimes interferred with their freedownward movement in the hoppers under the influence of gravity.

This invention is designed to overcome the defects noted above andobjects of such invention are to provide a novel form of lockingpmea-nsfor the plungers associated with the coin chutes in such a manner thatthe coins are permitted to freel wardly under the influence 0 gravit Ywithout being restricted by the locking means.

A further object of this invention is to I provide a novel form ofmanually actuated latching means for holding. the locking means out ofoperative position, and to provide means for releasing thislatchingmeans after the actuation of any plunger.

Further objects are to provide a novel form of coin delivery apparatusin which the locking means are each' intermittently raised, andpermitted to fallup on the actuation ofany plunger, so that there is anilltermittent release of pressure against the coins, thus permitting thecoins" to freely move downwardly intojthe desired position.

Further objects are to. provide a coin. delivery machine which has theabovedescribed characteristics, but which is of very simple and sturdyconstruction. I

in the accompanying drawings in which 1- Figure 1 is a side elevationpartly in sec tionof the machine. y T

Figure 2 is, a horizontal sectional view showing the locking dogs andthe releasing platef Referring to the drawings, it will be seen that acoindelivery machine has been provided in which a plurality of coinhoppers, indicated by the reference character 1, are provided for thereception of the coins 2. These coin hoppers are provided with slotsadjacent their lower ends through which the discharge arms or members 3may operate.

These members 3 are'preferably formed of a pair of pivotally joined armswhich are spring urged in opposite directions as disclosed, forinstance, 111 my Patent No. 1,401,-

133 of December 27, 1921, for coin delivery apparatus. These coindelivery plungers are actuated by means of an operative plunger 4. Theplunger 4 is preferably guided by roller bearings 5 with the rollers ofsaid bearings fit-ting wlthin slots formed as in the with a rock shaft 8which extends transversely across the machine, and is pivoted asindicated at 9, in the side frames 10 of the machine. The purpose ofthis rock shaft will hereinafter appear.

The plungers at are operated by means of links 11 pivotedat theirforward ends (to the plungers,and at their rear ends to arms 12 of therock bars or rock arms 13. These rock arms are depressed by means of thefeet 14 of the keys 15, as described in greater detail in the abovenotedpatent or in my co-pending application, Serial No. 92,248, filed March4:, 19:26; Obviously, the particular type of actuating key andassociated rock arms may Each of the plungers' a is provided with acammed upper surface 16 which slants forders are adapted to :be engagedby the locking dogs 18 under certain conditions, such locking dogsnormally occupying the ele vated position indicated in Figure 1.However, the locking dogs have their inner ends extending over thedownwardly turned portion 19 of a releasing plate 20, such plate beingpivoted, as indicated at 21. The plate is provided with a plurality ofnotches or slots 22 (see Figure 2) through which the plungers 4 project.The plate 20 is provided with a rearwardly projecting arm 23 which isadapted to be depressed by means of the foot 24 of a manually actuatedreleasing key 25. This releasing key is provided with any suitable formof latch, such as that indicated in Figure 1, for instance. It may benotched and adapted to be engaged by the upper end of a latching lever26. This lever 26 has its lower end joined by means of a link 27 withthe releasing rock shaft 8.

It is to be noted further, that each of the coin hoppers 1 is providedwith a coin engaging cam member 28 which is pivoted adjacent its upperend, as indicated at 29. This member 28 is provided with a circularlower portion 30 for a portion of its extent which is adapted to rockover the tops of the coins when the coins become nearly exhausted, asindicated in Figure 1. The lower end or rear end of the cammed member 28is provided with a projecting portion 31. This portion engages thedownwardly extending short levers 32 formed integrally with the lockinglevers 18. Preferably, these locking levers are hooked over a stationarytransverse rod 33 so that they may freely pivotupon such rod.

In the operation of the apparatus the keys 15 are depressed and. actuatethe appropriate plunger 4, or combination of plungers, by means of therock arm 13, and the links 11. The coins are dispensed in the usualmanner by this operation. However, it is particularly noted that at eachforward motion of any of the plungers 4, the cammed surface 16 thereofraises the plate 20 and, consequently, raises each of the locking dogs18. This relieves the pressure against the cammed members 28 and,consequently, relieves the'pressure against the coins, it being notedthat the coins are pressed into engagement with two forward points ofthe hoppers by means of the cam members 28. However, when the lockingdogs 18 are raised by the plate 20 upon the actuation of any plunger lthis pressure is relieved and the coins are permitted to fall freelydownwardly under the action of gravity and to thus correctly positionthemselves in their respective hoppers.

lVhen a hopper becomes partially exhausted, the lower portion 30 of thecammed member 28 swings over the upper edge of the coins and allows thecorresponding locking dog 18 to fall downwardly and to engage theshoulder 17 of its plunger 4. This looks the plunger against furtheroperation either singly or in combination with other plungers.

However, when it is desired to release the latching dog by means of themanual key 25, it is merely necessary to depress the key. This raisesthe plate 20 and releases the latching dog as the plate 20 extends underall of the latching dogs. The key 25 is held in its depressed positionby the mechanism described above. However, when any plunger 4 isprojecting forwardly the foot 7 thereof strikes the rock shaft 8 androcks such shaft forwardly. This draws the link 27 forwardly andreleases the latch for the key 25, allowing the key to sprin upwardly.

Thus it is impossi le for the operator to inadvertently leave thelatching dogs released, for the latching key is itself tripped upon eachoperation of the machine. Consequently, the chance of error in theoperation of the machine is materially reduced.

It has been found, from actual experiments conducted with thismechanism, that the raising of the latching dogs 18 upon the actuationof any plunger 4 permits the free falling of the coins in their hoppers,as it relieves them of any pressure due to the cammed members andlatching dogs.

It will be seen further, that the plate 20 performs a dual function. Inthe first place it acts as a releasing plate for each of the latchinqdogs and, in the second place, it lifts each of the dogs upon theoperation of any plunger, thus relieving pressure against the coins.

It will, therefore, be seen that a very simple and serviceable type ofcoin dispensing apparatus has been provided in which novel means areemployed for insuring the free positioning of the coins and also forreleasing the latching dogs temporarily during a single operation only.

Although the invention has been described in considerable detail, suchdescription is intended as illustrative rather than limiting as theinvention may be variously embodied.

I claim:

In a coin delivery machine, the combination of a plurality of coinhoppers, ejectors for removing coins from said hoppers, a plurality ofkeys for operating said ejectors, locking means controlled by the coinswith the hoppers for locking said ejectors when the coin supply is low,releasing means for releasing said locking means, means forautomatically locking said releasing means upon actuation of the samefor releasing said locking means, and means operated upon actuation ofany key for releasing said releasing means.

In testimony that I claim the foregoing 1 have hereunto set my hand atMilwaukee, in the county of Milwaukee and State of Visconsin.
